To all whom imag concern. j

Be it known that I, JAMES WALTER PRICE, a citizen of the United States, and a resident of Henryetta, in the county'of Okmulgee and State of Oklahoma, have made certain new` and useful Improvements in Shade-Rollers, of which the following is a specification. Y

One of theprincipal objects ofmy invention is to improve and simplify the construction and arrangement of parts of shadev rollers of the ratchet and pawl type, and Inore'particularly .of the type in which agravity actuated pawl is employed.

`Another object of the inventioncontemplates the provision of a pawl and ratchet mechanism ofV the class described, of such nature als to be readily applicable to Shade rollers of Standard construction. y A further Objectis to provide an improved shade roller of the'class described, designed with particular'reference `to advantages' of simplicity, durability, eiiiciency in operation and economyin manufacture and maintenance.

lVith these and other advantagesin view which will become apparent as the description proceeds, the invention resides in the construction, combination and arrangement of parts hereinafter 'more' fully described and claimed, andillustrated in the accompanying drawing, in which like characters of reference indicate like' parts throughout the severalgures, of which# j Figure l represents a top plan view of a Vshade roller constructed according to my invention. Y j

Fig. 2 represents an Aelevational view thereof, parts being shown insection to reveal the inside construction of the roller.

Referringmore particularly to the draw ing, the roller proper is indicated at 5, and

on this roller the shade l is wound in the usual` manner. At one end thev roller is equipped with a cap 7 having a round bearing pin 8 journaled in abracket 9, to be hereinafter more particularly described.

The opposite end of the roller has a cylindrical cap 10 mounted there0n,this cap being closed at itsouter end as at 11. `The end portion of thek roller on which the cap 10 is mounted is centrally bored as at 12 `for the reception of the rod 13, the inner end of which rotatably llits within a reduced socket 14 atthe innerend of the bore. The

in the end 11 ot the cap, and the extremity of the rod, beyond the cap, is liattened as at 15 and engages in a rectangular Opening 16 formed in a bracket 17 adjacent the outer The rod Vis thus held volve about the rod.` The openingzin the end 11 ofthe cap, is formed` by punching the metal inwardly through the operation of, suitable dies and there is thus formed around the opening an annular Shoulder 18 which forms a substantial bearing, and

Vagainst which the annular sleeve or collar 19 formed on the rod 13 bears. Y

. .Coiled upon this rod is a spring 2O which at its inner end is anchored on the rod as at The outer end of the spring engages in an eye 22 formed at the end of a tongue Vwhich is stamped inwardly fromvthe `end plate 11 of the cap` 10, the end of the spring being passed through the eye and turne upon itself as clearly shown in Figs. 6 and 7 `The `arrangement is such that-.when the curtain is pulled downwardly the cap `10 which, ofcourse, is anchored to and moves. u with the roller, in revolving about therod Y13, places the spring 2O `under tension so that whenthe roller is manipulated to unlock the pawl and ratchet mechanism hereinafter described, the tension of the spring will Operate to wind the curtain upon the roller. i 1 The bracket 17 at its inner end is provided with a laterally ektending portion 23 forminga base which receives the fastening device whereby the'bracket may be anchored to the wallfor window casing or to whatever Vobject the roller is to be mounted on. At a point removed from its forward end the d' bracket is Yformed withV an ear 0r tab which" is bent laterallytoubepositioned behind'the cap 10 of the roller, and then downwardly Vedgeof the body-27. and counterweight 28, is

lformed with the laterally extending pins 31 which4 project into horizontally alined open- Y ings'fprovided one inthe bracket 17 and the other inthe down-turned portion 25; of the ear formed onil the bracket. The pawl is thus pivoted upon a. luirizontal axis, and the Vactiongof gravity upon the counterweight 28 serves'tofnormally retain the' tongue 29 yof the pawl Vinen'gagementr with the cap v10V at thevouter edge or' corner of the latter.

Thebody of the: bracket 17 below the tongue V or earv formed on thel bracket, is

stamped inwardly toprovide` a lug I'32 which movement off the'tongue 29 of thepawlto 4wardithe'caplO, so that whenthe roller is'beingmounted in the bracketsnolincolprojects below the counter-weight 28 Yof the pawl which serves to, limit the outward venience` will be encountered through the pawl having swung outwardly too'far."v The tongue' 29 of thefpawl atitsfouter end Vis beveled as shown, to. present an'edge which is inclined to. the axis of theroller, andthe pawl extendsfin both directions beyond the ffeornerrformed atlthe junction' of thefcap lOwlith its closure plate 11. Thus, although the" notches 30 are frelatively shallow 'a positiveand eiii'cient lock for holding the roller .against rotationunder influence of" the spring, is, formed when'the tongue. 29 ofl the Y pawl engages eitherof 4thefnotches:' These V{notchesare in; width substantially equalfto "or slightly greater than thelthickness of the y'tonguef29 of thefpawl.r The curtain or shade having beenpu'lled downwardly, and being held in locked position by the pawl, yand. it -b'emg desired to'raise the'shade, thesameis grasped 'and pulledfdownwardly vsuiliciently "to cause disengagement oi'- thepawl from torOtate the cap# av slightl distance whereby the notch, and then by quickly releasing the j'dofwnward strain on 'the eurtainor shade,

the-springwillf 'cause lthe roller `to lrotate inf a direction for winding up the shade, and the speed oir'V the roller will be such that the notches will passthe :tongueof theV pawl, b e'- fore the latter, Lindenthe aetionofr gravity can engage in the notches,so that the roller will continue to wind up the curtain until its speed is reduced by thegraspoi' the op- `erator on Vthe shade, sufficiently/to `allwY of the paw-l engaging in one of the notches.

Thus the curtain or shadefmay be readily V adjusted to any desired-'position and` will be eiectively held in that;positionbyl the-foperation of the paw-l and ratchet-mechanism. Itghas, been found thatfthejndtches will skip the pawl, while theLcurtaiJfi` isbeing wound up, everlat a relatively` slow: speed of rotas' tion of the roller, andthis results in: the fact that the curtain orshade can be-.Veryfeasily and smoothly` adjusted.. .Thewstructure is such that friction. 'isy reduced,to` a minimum, j

and this fact lends.additionalease aindleff fectiveness to the operation ofthe4 invention.

One :advantage arising` from the construction which'. I provjideisgth'at shade rollers of standard construction inayrbe readily converted into t condition for use with the bracket and pawllwhich Tfprovid'e,,bylnerely removing lthefparts of the roller eXcepting the rod and spring :for controlling the; roller,

and by cuttingthe notches in theroller cap.

No other devicesl of'this.Lnaturew-ithiwhieh l am familiar, present this. advantaga since theyall involve .the use of rollers, orfappurtenanees thereof,` of specialy designtandQconstruction. i i

On the funderedgeofhthe bracket'17l is formed an inturned leaf 35 which extends below the pawlA and coperates with :the-ear Vformed-onthe bracketing-housing and protecting the pawl.
